Abstract (en)
[origin: WO2004034008A1] The invention concerns a reference leakage device (14) for leak snifter detector (1) equipped with a snifting tip (8) and a control unit (6). Said reference leakage device (14) comprises a gas reservoir (31) and a constriction (33) wherefrom is released a specific amount of test gas, at least during calibration. The invention is characterized in that in the constricted zone (33) is located a sensor (42) detecting the approach of the snifting tip and in that said device includes means for transmitting signals from the sensor to the control unit (6) of the leak detector.
